RYOBI ONE+ 18V Cordless Electrostatic Sprayer — 0.5 Gal Handheld, Adjustable Nozzle, Translucent Tank

The RYOBI ONE+ 18V Cordless Electrostatic 0.5 Gal. Sprayer (P2809BTL) is a handheld, battery-powered electrostatic sprayer that delivers adjustable droplet sizes and broad coverage for water-soluble disinfectants, cleaners, and many garden solutions.

This compact sprayer combines RYOBI's ONE+ battery platform with electrostatic assist to help coating reach surfaces more evenly and efficiently than conventional handheld sprayers. The lightweight design and translucent 1/2 gallon tank make it easy to fill, carry, and monitor fluid level. Note: battery and charger are sold separately; this listing is tool only and works with any RYOBI 18V ONE+ battery.

How does the electrostatic feature change coverage?

The sprayer’s electrostatic mode helps charged droplets adhere to surfaces for improved wraparound coverage compared with uncharged sprays. You can toggle the electrostatic function on or off depending on the chemical and application you prefer. It’s engineered for water-soluble disinfectants, general cleaning solutions, and many lawn-and-garden products—refer to the manufacturer’s compatibility chart for approved chemistries.

• Electrostatic on/off switch for flexible use
• Enhanced surface attraction for more uniform coverage
• Compatibility guidance available under info and guides

What spray patterns and droplet sizes can I expect?

The 3-in-1 adjustable nozzle selector offers Low, Medium, and High settings so you can tailor spray pattern and droplet size to the task. Lower settings produce finer droplets for closer, more delicate applications while higher settings deliver larger droplets and longer reach for wider or outdoor surfaces. Each setting lists an approximate spray distance to help you select the right coverage for your job.

• Low: ~65 microns, effective up to 2 ft.
• Medium: ~85 microns, effective up to 5 ft.
• High: ~160 microns, effective up to 10 ft.

How long will the sprayer run and what batteries work with it?

Run-time depends on the capacity of the RYOBI 18V ONE+ battery you use. With an 18V ONE+ 2.0 Ah or higher battery, the sprayer can deliver up to 30 tanks per charge under typical use. Because the sprayer is part of the ONE+ system, any RYOBI 18V ONE+ battery fits the tool, letting you choose higher-capacity packs for extended runtime.

• Works with all RYOBI 18V ONE+ batteries (battery and charger not included)
• Up to ~30 tanks per charge using a 2.0 Ah battery or larger
• Compatible with nozzle models ACES12, ACES13, ACES14

What maintenance and compatibility details should I know?

The sprayer features a translucent tank for easy fill-level checks and a tool-free nozzle adjustment for fast pattern changes. Some tanks and nozzles are not compatible, and RYOBI provides a compatibility chart—check it to ensure you’re using approved chemicals and replacement parts. The sprayer is covered by a 3-year manufacturer warranty for added peace of mind.

• Translucent 1/2 gallon tank for quick visual monitoring
• Tool-free nozzle changes and simple on/off electrostatic control
• Not compatible with tank models A95102, A95103 and nozzle models A95501–A95503
